Details:

Hello,

I found bug #9929 and bug #7200, maybe there are others. However, they seem to
deal with serves.

I configured my firewall to log and drop incoming and outgoing packets, which
source or destination address matches a private or otherwise not legal
address, see http://www.chip.de/c1_forum/thread.html?bwthreadid=847118 and
rfc3330.

When I run mldonkey, I see about 5 through 160 dropped outgoing packets per
hour, which destination address is a private or illegal one.

Although it's the duty of the router interfacing the internet to drop these
packets, it would be nice if mldonkey wouldn't at first place try to connect
to these hosts. -- option allow_local_network is off -- I guess, that mldonkey
is spending resources, time, memory, whatever, when it deals with these hosts,
one knows beforehand that they won't respond.

It would be nice to have a configuration option, that defaults to the
well-known illegal address ranges, so you can enable some local clients on
demand or add further locally well-known bad addresses.
